Are two cells the same if the order is different in excel

I used the same basic formula as HansVogelaar but placed it within a Lambda function and used MAP to define the array of sorted variables

Worksheet formula
= MAP(sepVar, SortVarλ)

where

SortVarλ
= LAMBDA(v, 
    TEXTJOIN(";", , SORT(TEXTSPLIT(v, , ";")))
  )

Once one has extracted the sorted values

one can count the number of unique strings or select one and test the others against it

= LET(
    strings,   MAP(sepVar, SortVarλ),
    refString, INDEX(strings,1),
    AND(strings = refString)
  )

YavuzDuran

=COLUMNS(
    UNIQUE(
        BYCOL(A1:D1,LAMBDA(ζ,TEXTJOIN("|",,SORT(TEXTSPLIT(ζ,,";"))))
        ),
    1)
)=1

I'd use a helper row. Let's say that your values are in D4, E4, etc.

Enter the following formula in D5, then fill to the right:

=TEXTJOIN(";", TRUE, SORT(TEXTSPLIT(D4, ";"), , , TRUE))

You can then check whether D5 = E5 etc.

Remark: if you use comma as decimal separator, use ; instead of , in the formula:

=TEXTJOIN(";"; TRUE; SORT(TEXTSPLIT(D4; ";"); ; ; TRUE))
